The air will enter the tube through a large duck-bill valve at bottom. When the tube is sufficiently filled with air, the diver can release it to the surface (while tied to a line) a built-in Over Pressure Relief Valve allows the tube to ascend without rupturing. This way a diver can signal he will soon be ready for pick-up, without going to the surface immediately. " Show more
